Abstract

PROBLEM TO BE SOLVED: To prevent the displacement of the medium of an adjacent bag body by disposing a waist supporting body between the plural independent bag bodies fitted inside the recessed part of the base and filled with the medium in the inside and an exterior body for covering the entire base. SOLUTION: The base 11 is formed by foamed urethane and the recessed part 12 is formed on the surface side. Inside the recessed part 12, the three independent bag bodies 13A, 13B and 13C are disposed respectively corresponding to the back part, hip part and foot part of a person H. Further, the waist part supporting body 13D is disposed between the bag body 13A and the bag body 13B and the waist part supporting body 13D is formed by filling water or gel formed by impregnating water absorptive resin with the water or the other medium in a bag from an injection port. Then, the base 11 is covered with the exterior body 19 which is a quilting worked cloth and this water mattress 10 is completed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mattress.

[0002]

2. Description of the Related Art As shown in FIG. 1, a conventional water mattress 10 has a base 11 formed of a foamed resin.
Three independent bags 13A, 13B and 13C in which a medium is sealed are fitted in the concave portions 12 of the first and second embodiments. And
The water mattress 10 is configured by covering the entire base 11 with the exterior body 14 that is a quilted fabric.

[0003] As shown in FIG.
3A, 13B, 13C are the back, buttocks,
Corresponding to the foot, extreme depression of the body, deformation and shaking of the bag body are suppressed without impairing the body pressure dispersibility.

[0004]

However, the bag 13A
The boundary between the bag 13B and the bag 13B is just around the waist of the person H, and as shown by the arrow in FIG. 2, the medium inside the bag 13A for supporting the back and the bag 13B for supporting the buttocks. Both media concentratedly acted on the waist, giving the user a feeling of oppression.

Therefore, an object of the present invention is to provide a mattress that does not have such a problem.

[0006]

Means for Solving the Problems In order to solve the above technical problem, the technical means taken in the invention according to claim 1 is a base having a concave portion formed on the front surface side, fitted in the concave portion, and A mattress includes a plurality of independent bags in which a medium is sealed, a waist support provided between the bags, and an exterior covering the entire base.

[0007]

In the structure of the first aspect, since the waist support prevents displacement of the medium in the adjacent bag, there is no pressure on the waist.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a mattress according to the present invention will be described below with reference to the accompanying drawings.

In FIG. 3, a water mattress 10 is shown.
Includes a base 11. The base 11 is formed of urethane foam, and has a concave portion 12 on the surface side. Thus, in the recess 12 there are three independent bags 13
A, 13B, and 13C are provided. Bag body 13A-1
3B and 13C correspond to the back, buttocks, and feet of the person H, respectively.

The bag body 13A (13B, 13C) is formed by impregnating water or a water-absorbing resin with water from a filler (not shown) in a bag made of a flexible material, for example, vinyl, or the like. Is formed by enclosing the medium.

A waist support 13D is provided between the bag 13A and the bag 13B. The waist support 13D is
It is formed by enclosing a gel or other medium formed by impregnating water or a water-absorbent resin with water from an inlet (not shown) in a bag.

The base 11 on which the members are arranged in the manner described above is covered with the exterior body 19 which is a quilted fabric, and thus the water mattress 10 is completed.

When the person H lies on the water mattress 10, the medium in the bag 13A and the medium in the bag 13B flow to the right and left sides of the figure, respectively, due to the action of the force from the person H. Since the force caused by this flow is blocked by the waist support 13D, it hardly acts on a person. Therefore, there is no compression on the waist.

As shown in FIG. 4, a waist support 18 made of a resin foam may be used instead of the bag-like waist support 13D as described above. In addition, each bag 13A, 13
The medium in B.13C may be air. That is, the present invention can be applied to an air mattress.
